They mark positions, given by the manufacturers, where there are no internal systems to delay entry, or dangerous for emergency crews, into the aircraft if it proves necessary to cut into the fuselage for access purposes, you cannot always use the doors/emergency exits in an accident. I think it only applies to aircraft above 3,600kgs and/or those used for the purposes of public transport. Emergency Exits are also (legal requirement) marked on the outside of the aircraft. Hope this is of help/interest. Regards, Paul (Whiteman) whose views are mine and mine alone""
